I'm currently having some serious brakes problems. I've now opened up and had a look at the brakes on both the rear driver and passenger side. The biggest problem at the moment is, the rear passenger side wheel area is leaking brake fluid. I can't quite identify what the tubing/ brake line is where the leak is coming from. In my manuals/ diagrams, there's a brake fluid line that goes into the top of the caliper area, but the leak is coming from a different line that runs underneath. I've attached an image here. It's the tube/ line right in the center of the image.

Everything looks intact on the driver's side. I have pads to do a replacement but haven't been able to rotate the caliper on the passenger side to do the installation. The top caliper pin ("rear brake pin retainer") loosens easily, but the bottom one may be stuck/ seized.

If someone can identify what this component is that's leaking that'd be a start.

The piston on the rear caliper itself may be leaking. If i were you i would
get a replacement caliper. Once you unstick the stuck caliper pins,
Get some proper high temp pin lube and lube them up (make sure you do
the other side too) Most people with rear disks that have not had them
done in awhile probably have a least one stuck caliper pin

You will have fun with the emergency brake curly spring.
you will also need to get a caliper tool to screw in the caliper
(DONT push it in like a front caliper) The tool looks like a little open cube

If you really unsure whats leaking, get some good degreaser and spray
it down and wash it all off. Then drive it for awhile and look for th fresh
leaks

As others have said, it could be the caliper, but it looks like it might be leaking where the rubber hose connects to the caliper itself or from the hose itself.

Whatever the case, just get a new caliper with a new bracket (they don't always come together, make certain to ask) and save yourself some headaches. Rebuilding/unseizing stuck brake parts is worthless IMO with the cheap cost of new parts, especially for these cars.

If you want to go the extra mile, grab a brake hose for that side too and install it. Don't forget to bleed the system when you're done!

I have at this point a used right rear brake caliper off of Ebay. Not sure if a used caliper was the best decision, but it seems to be in better shape than the caliper that is in the vehicle right now. Maybe I'll post a picture of it. I also have a pair of new rotors coming.

One problem that I'm experiencing right now is some ABS malfunction. It happens especially when the brake fluid is low. Something triggers the ABS at low speeds while coming to a stop, and I can end up losing control of the vehicle for several seconds. Actually, I'm not sure if the ABS was really ever working properly in the past two years, and I'd like to get a better understanding of what this ABS problem is. I guess there is an ABS sensor somewhere in the rear right wheel or brake system, which may be dirty. Is that about right? Is it a good idea to disable the ABS by pulling the fuse?

If you are talking about the rubber hose, that is you "return" line, you can just replace it or is it just the connection between the hose and the caliper?

I believe that it's the parking cable, which goes through a hole in the caliper assembly. The connection between the hose and the caliper isn't in this image, it's further up toward the other caliper pin. One problem is, it's hard to engage these bolts and not too clear in the manuals about the correct sockets.
